Does Rebound Tonometry Probe Misalignment Modify Intraocular Pressure Measurements in Human Eyes?
Figure 4
Difference versus mean plot illustrating the comparison between IOP measurements taken with the iCare tonometer at the baseline position (CC) and at specified lateral deviations. (a) iCare tonometer probe was laterally displaced 2 mm nasally from the centre of the cornea. (b) iCare tonometer probe was laterally displaced 2 mm temporally from the centre of the cornea. The solid line represents the mean bias, and the dashed lines represent the 95% limits of agreement with the dotted regression line displayed. Lateral deviation of the probe showed no significant correlation with measures at CC in nasal or temporal positions.
